A biological scaffold in the present invention comprises a main body, a biological material layer, and an optional tissue adhesive layer. The main body at least has a non-constituted collagen matrix. The biological material layer is coated at least on a surface of the main body, and the tissue adhesive layer is disposed at least on another surface of the main body. When the biological scaffold is adhered to a tissue through the tissue adhesive layer, a plurality of cells move from the tissue to either the adhesive layer or the biological material layer for tissue repairing or regeneration. |
